Batrium BMS Questions

Check out Daromers vid on setting up the system if you haven't already

Thank you!  I must have missed this video of his.

Use bigger cables;-P

@bfleury

I read you have the storedge system.
Why shut the system down when the grid goes off?

Here I'm preparing my battery bank to test it on my solartracker with 700pW power. If this work and I understand the system I was planing to make a 10Kw ba hooked on SolarEdge inverter/Storedge. But do you have LG Chem battery or tesla's powerwall.


Hi,

I paid extra for the StorEdge to use a Tesla Powerwall.  I've had one on order since they first came out, since the 1st version I paid the downpayment for the PowerWall2 and just recently got a email saying I may get mine after Oct.    I cancelled the order after finding this site and decided to do one myself.   You have to add the cost of changing your service again in Milwaukee area, plus the required "Commissioning, Authorized - Licensed contractor installation costs". They what you to go from 2 meters to 3 meters so they know what your battery is doing?   They had it so you had to have 5 meters here, but the contractors got them to go with the 3.  I have to pay a monthly per meter charge here on them also.

I then found out that the only battery the StorEdge will accept is the LG and Tesla, the tech help people were pretty short with me and just stated it was impossible to run any other type of battery power into the unit to power the critical load output.   So it will be cheaper to save the Tesla costs and just build my own wall and install a separate inverter system for it.

PS.  I did figure a way to get around their restrictions to use the StorEdge.  I ordered a P400 converter, added it to a string and instead of attaching a solar panel to it, I'm just feeding it battery power.   It does have the same issue of being shut down when the grid goes down though.

Hope this helps you.

In the Netherlands you can install what you will the only rule is that if you produce more electricity than you use you get normal KWh price but after 5000Kwh you will get 7 cent a KWh. 

As far I can see the Storedge will work with the Batrium bms because It can talks like LG battery. I think if you have the whole SolarEdge system is a good investment because of the warranty. Can you tell me if your supplier setup the panels specially for the Storedge? I mean not big strings but parallel groups?

AZ_Tekkie  Im one of the guys working on the system alot yes. And i have done some scripts that can controll them from for instance a raspberry pi. There havent been much done last 2-3 weeks but we picked up the work today again and hope to get going. For now we only have generic logging but working on controlling the units.

There is also work done with Batriums own expander board that with the Batrium as a start will be able to control the PIP4048.

If you have any questions just ask and me, Peter, Jaron or any of the other will answer Smile

I have the SE7600 inverter and the panels each have a solaredge P400 optimizer.  The inverter will take two strings.  I have one string of 9 panels and the other 22 panels.  The panels are Hanwha Q-cell  L-G4.2  330w.  If you figure out how to interface a DIY powerwall to it, please let me know.

Today i have received email back from SolarEdge. 

It's not possible too use a 48V battery on the StorEdge interface because it need 400V.....
I'm a little disappointed.

Hi Joost2,

That is the same thing they told me.   I will probably get a couple more optimizers ( I got a P400 for around $65 ) add them to my smaller string and feed the battery power into them.   With three I can feed in around 1200w.

Something t think about.    Wink

Well just got my batruim system and I have a problem.
I have just the watchmon connected via usb to do some basic set up, but whenever i try to save the settings its asked for a passcode. Where is this as nothing i have tried works and i can find no mention of it anywhere on there site.
Someone please put me out of my misery.
